Okay, so these guys are nuts and I’ve just discovered anything thing I’ll never do. Extreme video shows a man testing his parkour skills on a skyscraper with no safety gear and it’s almost too hard to watch! The man allegedly from Russia dangles from the edge of the building and holds onto his friend’s arm as he further wonders towards the edge. I don’t know about you, but I’m getting nauseous just watching this. This is the most extreme video I’ve seen in a while. Definitely something you’ll want to share with your friends!
